The UMTS Network planning is a concepts used to do coverage and capacity study for specific area.

Network Design should be optimum.

planners should have ability of radio propagation prediction.

Overview Overview

Page 3: Optimum Design Mod2

Problems Facing UMTS Network Design:

Environmental constraints. Planning future. Uncertainty traffic growth and service. Cost.

Case studyCase study Geographically located in the north-east of Khartoum.

The estimated total area is 5060 Km²(selected 43Km²)

characteristics of the selected area:

Radio Network Planning (RNP)

Page 7: Optimum Design Mod2

Coverage Plan:to identify the cell coverage (Radius)

then the required number of Node

Bs (RBSs).

Capacity Plan:to grantee enough resources for the

available users.

Page 8: Optimum Design Mod2

General RNP tool requirements: -Importing sites.-Editing sites and Cells.-Simulating Link Performance.-Analyzing the results.-Reporting.-Interworking with other Tools.

Atoll:Atoll is a Windows based radio network planning (RNP) tool supporting wireless telecom operators during the whole network lifetime.

Design Steps:- 1.Calculation:PL= Node B Transmission Power

+ Node B Antenna Gain - Cable Loss - Penetration Loss - Body Loss + UE Antenna Gain (dB)+SHO Gain –SHO Gain -Interference Margin -UE Reception Sensitivity PL= 36+18-3-15-3+0+3-3-5-5-(-104) = 127 dB

α= (PL-61-20 log f)/20 =2.9675

R=10α

R =0.79km=800m

Area=3/2 √ 3 R² =2.2 Km²

Number of Sites = 43/2.2=19.54= 20 Sites.
